Affirmative conclusion from a negative premise:

Formal Fallacy
Definition Example
When a categorical syllogism has a positive conclusion, but at least one negative premise. I don’t eat meat. People who eat meat have no compassion. Therefore, I have compassion.
  Notes
 

If A ⊄ B and B ⊄ C then A ⊂ C.

This fallacy is made clear when we follow this same form and say “If I’m not a goose, and geese don’t play bingo, therefore I play bingo.”


Case Study One

This fallacy is often invoked in the context of tribalism in which the following type of argument is implicitly made.

We don’t do X.
People who do X are bad.
Therefore, we are good.


Keep in mind that a fallacious argument does not entail an erroneous position.
